hi there,
on my site I have elements which are different sizes in width. how can I have them so they are all same width and height in across all devices.
here is a screenshot http://prntscr.com/ndgjq7
ideally I would want the borders right to the edges of the screen on mobile and laptop/ monitor. on the left it should touch the blue header border and on right it should be to the edge in desktop. the content however should stay in the middle
